Gaga tweeted from her hospital bed:"Going in for surgery now. Thank you so much for sending me love and support. I will be dreaming of you."

After coming round from the operation she took to her Little Monsters blog to thank her fans, and promised them this is just a temporary bump in the road for her live shows.

She wrote: "Everything happened so fast, but when it came time to face it I reflected on the many stories and experiences you've shared with me about your lives. You have completely blown my mind.

"As they wheeled me into surgery today, I thought about all of your pain and perseverance, your unique family situations, school environments, health issues, homelessness, identity struggles - sometimes you are so brave that it terrifies me.

"So I thought to myself, I'm alive, I'm living my dream, and this is just a bump in the road. I'm grateful because this is temporary, and for some it is not. You have changed my life. I love you and am proud to be a part of your lives. If you can do it, I can do it too, and if we stick together we can get through anything."

The 26-year-old singer - who has been wheelchair bound by the injury - previously apologised to fans for cancelling some of her concerts on doctors orders.
